Question: Is it possible to know which one of my hundreds if not
thousands of email addresses are invalid without ever going through my
return to sender address unknown emails or the receiver of the email
ever responding?

Do you mean using PHP?
if you do mean using php - you cannot do this *accurately* because an
email address may be valid in it's format and still be non existent or
temporarily unavailable.
